COVERING FOR CABLE-CONDUITS.

SPECIFICATION forming part of Letters Patent No. 462,135, dated October27, 1891.

Application filed April 23, 1891'.

To @ZZ whom it ritay concern:

Be it known that I, HARRY HUGHES, of Abilene, in the county of Dickinsonand State of Kansas, have invented a new and Improved Covering for CableConduits, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a a new and improved coveringwhich is simple and durable in construction, arranged to be opened bythe pilot of the car, and adapted to be automatically closed by the sameafter the grip has passed.

The invention consists of a series of plates fitted to slide in angularbearings across the slot, and levers, each connected bya link with aplate and extendingin the path ofthe pilot at the next following plate.l

The invention also consists of certain parts and details andcombinations of the same, as willbe described hereinafter, and thenpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan view of the improvement with parts removed and partsin section. Fig. 2 is a like view of the same in a different position.Fig. 3 is a sectional side elevation of the same. Fig. 4 is a transversesect-ion of the same on the line 0c ot' Fig. 3, and Fig. 5 is a detailperspective view of two adjacent slid'- in g plates.

The cable-conduit A, of any approved construction, is provided in itstop with the usual slot B, adapted to be covered by a series of plates CC C2 C3, dvc., arranged one in front of the other and iitted to slidetransversely in a recess D, formed on top of the conduit A at one sideof the slot B, as is plainly illustrated in the drawings. The recess Dis adapted tobe closed on top by suitable covering-plates E, resting onthe rabbets at the sides of the said recess.

Each of the plates C C C2 C3, &c.,is fitted to slide in bearings F,fixed in the recess D and arranged angularly to the slot, as is plainly7illustrated in Figs. l and 2. The bearings F extend into angularrecesses or grooves F in the said plate C C, ttc., so that the saidplates in their transverse movement slide anseria No. 390,110. (Nomodel.)

gularly to open and close the slot B. The ends G and G of each plate arearranged at angles to the bearings F, the t'ront end G of each platebeing provided ou its outermost corner with a square offset G2 for apurpose hereinafter more fully described. This square offset G2 extendsunder a corresponding recess or notch in the end G of the precedingplate, as clearly shown in Figs 3 and 5, so that the plates can readilyopen and close without being hindered bythe said offset G2.

Each of the plates C C C2, &c.,is connected at its rear end G with alink H, extending under the next following plate and pivotally connectedwith a lever I, fulcruxned at I to the bottom of the recess D, asisplainly illustrated in Fig. Il. The front end I2 of the lever Iextends into the slot Band is adapted to be engaged by a pilot J,secured tothe under side of the car K in front of the grip L.

The operation is as follows: The several plates C C C2 C3, 8:0., intheir normal position close the slot D, and when the car K travelsforward in the direction of the arrow a the pilot J engages the firstplate C at the projection G2 of the front corner, so that a pressure isexerted on this plate, which is thereby caused to slide transversely inits angular bearings F. This movement of the plate opens the slot forthe passage of the grip L, and the plate thus opened remains openfor ashort time-that is, until the pilot J has opened in a similar manner thenext following plate and travels a little past the lniddle of the saidplate, when it engages the projecting end 12 of the lever I, so that thelatterreceives a swinging motion in the direction of the arrow b',whereby the link H is pushed backward, thereby causing the plate C firstopened to slide transversely to its former position, so as to close theslot B. This operation is repeated with the successive plates-that is, apreceding plate is closed when the pilot-J has traveled to about themiddle of the' following plate, at which the lever I, operating thepreceding plate, is engaged and actuated by the pilot J. Thus it will beseen that the slot B remains closed at all times after the car haspassed, so as to prevent injury to animals or vehicles by being caughtin the said slot B. The pilotJ is preferably held detachably on the carK,.so that TOO it can be moved to either side of the grip L Whenever thecar is turned or travels on the return trip. It Will further be seenthat n0 springs Whatever are required for accomplishing the movement of4the plates C, doe., the latter being actuated by direct and positivemechanism.

Having thus described my invention, What I claim as new, and desire tosecure by Letters Patent, is-

l. A covering for cable-conduits, provided with a series of platesfitted to slidein angular bearings across tlie conduit-slot, the saidplates being opened and closed by a pilot held on the car, substantiallyas shown and described.

2. In a covering for cable-conduits, the cornloination, with a seriesofhorizontally-sliding plates adapted to be moved from over the slot oftheconduit, by a pilot on the car engaging the plates, of levers connectedwith said plates for engagement with the pilot for moving.A the platesacross said slot, substantiallyl as described.

3. In a covering for cable-conduits, the combination, with a series ofplates, of angular bearings in which the said plates are fitted to slideto open and close the conduit-slot, alink pivotally connected with aplate at the rear end, and a lever pivotally connected with the saidlink and extending at its free end into the conduit-slot in the path ofa pilot on the car, substantially as shown and described.

4.` Ina covering t'or cable-con duits, the combination, with IiXedangular bearings, of a series of plates fitted to slide in the saidangular bearings to open and close the conduitslot, each plate beingformed with angular ends, a link pivotally connected with the rear endof each plate, and a lever pivotallyconnected with each link andarranged under the next following plate and having its free end extendedinto the cond uit-slot to be engaged by a pilot on the car to close thepreceding plate, substantiallyas shown and,l described.
